In that stillness, that freezing of time and of the world, only the slight, monk-like figure of the Harvester moved normally, in real-time. It did not move hurriedly. It had an economy of movement, an assured, almost peaceful pace.
 Â
Everything will be all right, Smith.
  The words rose in his mind, they were bubbles in water, and a strange peace came over Smith then. His world expanded outwards, beyond the city, beyond the Earth, past the moon and the planets and the sun and outwards still. Star systems rushed by, strange sights, engorged suns and empty spaces that swallowed the matter around them, clouds where stars were being born, red suns, dying, worlds beyond countâ¦
 Â
Everything will be all right.
⢠⢠⢠â¢
The observer felt that its time here on this curious world was coming to an end but was impressed by the human-laid trap, which suggested several things to him.
 Â
That the humans, or some faction of humans, had indeed deducted the observer's arrival, and its purpose.
 Â
And were determined to capture him, either to prevent him from achieving his mission, or to study him, or both.
 Â
Which was exciting news to the observer, even though, having observed, as it were, an entire chain of circumstances and events â of people â that led him to the knowledge he
would
be observed, he
would
be deduced, this was still material evidence, and first-hand. A postscript to his report, he thought, almost fondly.
 Â
There was little that was useful in the minds of the distorted humans, however. Whatever process they had undergone, this serum the observer had found mention of in several of the voices in his head, it had done irreparable damage to the complex, delicate webwork of their brains. He took from them with the same compassion he took from the dying he had met along the burning city, but there were no whole minds here, nothing but fragments, which he extracted with care.
 Â
They were frozen, or near frozen â the observer had kicked into a higher mode for a short duration, had initiated, in fact, the beginning of the process that would end his time here, on this earth â and he took from them with ease, sinking the data-spike into their brains, releasing the data left in there while permanently terminating the living tissue.
 Â
In slow motion, the bodies crumpled to the ground, one by one, as the observer moved amongst them like a gardener, unhurriedly pruning back leaves.
 Â
At last it was done; only the other remained, this short compact human who had come down from the sky. He recognised him, crisscrossing references from the voices in his head, saw him young, saw him trained, saw him meeting Mycroft for the first time, in a Soho street with the rain falling down, saw him falling for Alice, by the side of a Venice canal, saw him operational, then, a brilliant young shadow executive: Aden, Zanzibar, Vientiane, Moscow, a spell in Tenochtitlan, cultural attaché at the embassy running interference inside the Aztec capital â back in London after an operation went bad in Tunis, then the fruitful collaboration with the Byron automaton, handling internal security, foreign networks, becoming Mycroft's right-hand man and Alice's loverâ
 Â
The man was an enigma, the observer thought with curiosity. He could read his life like a dossier, perfectly laid out, but what he thought, wondered, wanted â this the observer had no access to, and he was not surprised to find out that he wanted it.
 Â
He was, after all, an observer.
 Â
He turned at last to the vehicle, which was powered by a primitive internal combustion engine â advanced for this society of coal and steam â using what the humans called diesel, after a German scientist who seemed embroiled in the machinations of the man they called Babbage, and who the observer would have liked to have met.
 Â
The observer reached for the front door of the vehicle and yanked it open and slid inside. There was one solitary man sitting in the driver seat, a panel of instruments before him, still frozen in slow-time, his hand reaching out in tiny increments towards the controls. Gently, almost with affection, the observer added him to his collection and, a moment later, laid its corpse down gently against the seat. A new voice in his head, but he shut it down â a flavourful one, this one, a conman and a writer, Karl May by name, and Krupp's agent â he added a new strand to the story the observer was to carry back, and for that the observer was grateful.
 Â
The device had been in May's lap. Now the observer retrieved it. He initiated a communication channel with the ancient thing, establishing a protocol and negotiating a handshake despite the device's initial sus
picions. He found himself fascinated by what he found, and it was with some regret that he at last shut it down.
 Â
When he stepped out of the vehicle, the device safely locked, the an
cient tripod machines had wavered against the skyline and then, as though in relief, disappeared.
 Â
They did not belong here, they came from a place unexplored for untold millennia, perhaps aeons. The observer wondered which observer would get the chance to go there, when he returned and submitted himself â that is, his report.
 Â
He hoped it would be himâ¦
 Â
There had been a name for that world. In human speech, it may sound a little like
Croatoan
.
 Â
It was done. The observer let slow-time go, and time sped upâ
Â
Smith stood very still, in a changed world. The creatures that, a moment earlier, had threatened him, were now on the ground, and they were dead. The skyline was different, the tripod machines were gone. The city still burned, but it would recover, it would lick its wounds. It always had, before.
  Smith stood alone by the black vehicle, alone but for that otherworldly thing, that
Erntemaschine.
  He looked at the Harvester and it was like looking at a mirror, it was like looking at himself. He hesitated. The machine waited, patient, revealing nothing.
  "Alice?" Smith said.
  "Smith," she said, out of the
Erntemaschine
's mouth. There was a load of sadness and pain in her voice he found hard to bear. He thought of his agreement with the Bookman, the other's promises of raising Alice for him, of bringing her back from the dead, and he realised the futility of that offer; he knew then he could not bring the Harvester back with him, that Alice was lost to him.
  The
Erntemaschine
waited, patient, but looking at Smith in a certain way that Smith recognised.
  "I can't bring you back," Smith said, and that admission, of his own helplessness, hurt as it left his mouth, like jagged edges of broken glass cutting through his throat and tongue.
  "Smithâ¦"
  The Harvester waited, knowing, patient.
  Smith nodded, once.
  There was only one way for them to be together again.
Â
 Â
The observer was satisfied. He knelt by the corpse, gently prying the data-spike out of the dead man's head. Inside him a new voice joined the rest, intertwining with one of the other voices in particular. The observer stood up, then, recognising in that small, unremarkable corpse something akin to his own identity, a tool and a servant who yet took a great joy in fulfilling its tasks. Smith⦠even the name was appropriate, almost a title, like Observer⦠he silenced the voices. Almost. Almostâ¦
 Â
He just had to wait for his other self to finish, at last, the job.

"Mr Houdini," the voice said. "Welcome to Transylvania."
  The voice had an awful, scratched quality to it. Harry tried to open his eyes. They felt gummed together, and his mouth tasted of razorblades and old blood.
  Alive. Somehow, he was still alive.
  He opened his eyes.
  Shapes slowly resolved in the semi-darkness of the room. The light was red, the air felt humid, almost moist. He found himself sweating. It was very hot, very humid, like aâ¦
  He sat up. Everything hurt. His hands on his head, his fingers through his hair â realising it was longer now, that he must have been in that crate, that coffin, for a long time, longer than he thought. He looked around him.
  A large, dark crypt it seemed to Harry, illuminated by artificial red light, and quiet, too quiet. Around him, everywhere he looked, orchids grew, a huge variety of colours and shapes, like living things, waiting, watching⦠hungry. He suppressed a shudder; could not see another person there. So who had spoken?
  "Who are you?" he said.
  A strange sound, of bellows, of air going in and out, in and out. A beat, weak and yet amplified, filling up the cavern, like the sound of an old, human heart. Harry squinted into the darkness.
  "Hello?" he said.
  His voice sounded lonely and thin in that underground greenhouse. The sound of bellows, of air being breathed, as by a vast machine. The pounding of that fragile heart, and Harry's own heart responding, fear rising, palms damp, and he tried to calm himself, to look inwards, trying to think how he could escape, whenâ
  A shape, a sliver of shadow materialising out of the darkness, moving gradually closer, growing in sizeâ
  And Harry had to suppress a scream, a thing out of nightmare coming towards him, features slowly resolving, and in the dim red light of the cavern he sawâ
  It had been a man, once. Now it sat there, welded into its chair, a thing neither human nor machineâ¦
  Pipes came out of its back, fed into its lungs, and large bellows moved like butterfly wings, fluttering, pumping air through that ancient, wizened body, keeping it aliveâ¦
  Glass tubes in which red blood bubbled, the tubes in turn feeding into the old man's arms, his handsâ¦
  The face was like a skull, what skin there was hung loosely, yellow like gas flames. There was no hair but thick black wires came out of that skull and trailed upwards, connected once again to the cloud of machines that engulfed this being, this creature, this once-living thing.
  It was ancient, it should have died long ago, it was a mummified human body kept alive by its machines, it wasâ
  "Whoâ¦" Harry whispered, and his throat felt raw and clogged, and a chemical taste, suffusing, so it seemed to him, the very air he breathed, lodged itself in his mouth, "What⦠Who are you?"
  The mouth in that faceless skull barely moved, and yet the creature in the chair spoke, its voice amplified through unseen machines. Like an Edison recording, the words were slightly disjointed, scratchy, put together from separate recordings and meshed into a single voice. And now he saw the ancient fingers, bone-like, tapping on a keypad of some sort, like brass buttons there, within reach â producing the sounds he heard, he realised. The man was no longer capable of speaking in his own voice.
  "I am Charles Babbage," the mechanical voice said.
  Harry scrambled away from the creature. He felt as if the thing was after him, after his youth â that soon it would pounce on him, attach fang-like devices to his neck, empty him of blood, feast on himâ
  "Really, Mr Houdini," the voice said, and the eyes â the eyes! â they were terribly alive, large and moist like smooth pebbles in a stream, they looked at him, with amusement and curiosity, they were the only living thing in that ruined face â "there is nothing to fear."
  The voice chuckled, the same old scratched recording, and the chair on wheels moved closer, and the man loomed before Harry now, and looked at him, his head tilted slightly to one side. Harry could see blood flowing, in measured doses, through the transparent tubes that fed in and out of Babbage's arms.
  "We are not so unlike, you and I," Babbage said.
  Harry stood up. His muscles didn't ache as much as he had expected. And, in fact, there had been no waste left in the coffin⦠which he didn't want to think about, at just that moment. He towered over the old man. "You should be dead," he said.
  "And so," said Babbage, "should you."
  Harry stopped, his rage drying. "What do you mean?" he whispered, and again he heard Babbage laugh, that old recorded sound echoing through the greenhouse. They were alone but for the orchids. "How many times have you died now, Mr Houdini?" Babbage said.
  "I don'tâ"
  "Know what I mean? Oh, but I think you do, quite well," Babbage said. "Tell me, when was it that the Bookman found you?"
  "I will notâ"
  Cold sweat, and fear, it couldn't be, he wasn't likeâ
  "Answer my questions? Or do you not know the answers?" Those large, wet, extraordinary eyes gazed up at him, almost in admiration. "I can answer your questions for you, Mr Houdini. Would you like me to? Would you like to know, just what you are?"
  The eyes, he saw, were no longer looking at him but behind him, behind his shoulder, and he suddenly had that awful feeling that something, someone, was standing behind him, so close that, almost, he could feel their breath on his skin. He tensed.
  "I know who I am," Harry said.
  "I will show you yourself," Babbage said, in a voice almost sad. "In a handful of dustâ¦" His head moved, a fraction. "Take him," he said.
  Now Harry turned, ready to fightâ
  Behind him loomed a huge, bald-headed human, with a scar running down one cheek. The man smiled at him, without malice, then a hand like a meat hook descended and grabbed him by the neck and lifted him up.
